BOTTLE-CLEANING MACHINE.

Specification of Letters Patent.

Patented Apr. 15, 1913.

Application filed November 19, 1912. Serial No. 732,311.

To all whom it may concern Be it known that I, ANDERS ANDERSEN PINDsTorTE, director, a subject of the Kingdom of Denmark, residing at Frederiksberg Alle 62, F rederiksberg, near Copenhagen, Denmark, have invented certain new and useful Improvements in Bottle-Cleaning Ma.- chines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention has for its object an improved bottle cleaning machine, in which the interior of the bottles is cleaned by means of compressed air and liquid and the outer surface of the bottles is cleaned by means of rinse water and rotary brush-disks.

The drawing illustrates a constructional form of the improved machine.

Figure 1 is a vertical section through parts of said machine and Fig. 2 a transverse section on line AB Fig. 1.

a is the rinse-water reservoir and b a horizontal shaft mounted in bearings above said reservoir. On the shaft 6 are mounted two concentrically arranged, ringshaped, independent, closed chambers c and d, each of which by means of partitions f is divided into compartments separated from one another. The ends of the shaft 6 are hollow. The hollow end 6 is connected to a reservoir for water under pressure (not shown) and the hollow end 9' with a compressed air reservoir. (Not shown). The hollow end e is through channels 2' provided with cocks h connected to each of the compartments of the chamber 0, and the hollow end 9 is through channels j provided with cocks it connected to each of the compartments of the chamber d. Rinse pipes in and 1 lead from the chambers 0 and (Z, which rinse pipes are in pairs inserted one within another. The bottles are placed on the rinse pipes so that the latter project through the necks of the bottles and into the interior thereof, whereby the bottles are carried by said rinse pipes through which water under pressure and compressed air are supplied to the bottles when the cooks h and h are opened. v

In the rinse water reservoir rotary brush The mixture of liquid and compressed air,

entering the bottles when the cooks are opened, cleans the interior of the bottles. During the upward movement of the bottles from the rinse water reservoir water jets may be directed against the outer surface of the bottles.

The constructional details described and illustrated may of course be varied.

Claims.
